Abstract
A skid system for carrying a charge in a pusher or walking-beam furnace incorporating a cooled skid pipe 3 and at least one rider 1 fitted on the skid pipe for carrying the charge in the furnace is, for permanent and effective insulation of the cooled skid pipe in the rider area designed for the rider 1 to comprise a charge-carrying support land and two channel-shaped leg portions 2 adjoining the land, the leg portions surrounding part of the periphery of the cooled skid pipe 3 in a spaced-apart relationship and for the space between the cooled skid pipe 3 and the inner surfaces of the leg portions 2 to form insulating spaces 4 filled with a thermal insulation material 4'.
Claims21
A skid system for carrying a charge travelling through a heat-treatment furnace, and more particularly a pusher furnace or a walking-beam furnace, said skid system comprising:
- a cooled skid pipe,
- at least one metal rider fitted on said skid pipe for supporting said charge in said furnace;
- said rider comprises an integral one piece casting having a charge-carrying land and channel-shaped leg portions adjoining said land at opposite sides thereof, said leg portions having inner surfaces surrounding part of the periphery of said cooled skid pipe in a spaced-apart relationship;
- a heat conducting support means below said land, extending along and between said skid pipe and said rider, said support means providing a direct heat conducting path between said skid pipe and said rider;
- opposite sides of said support means, said inner surfaces of said leg portions and the adjacent periphery of said skid pipe defining insulating spaces on opposite sides of said support means;
- and
- thermal insulating material substantially filling said spaces between said cooled skid pipe and said inner surfaces.
